Why are connected in parallel electrical loads in motor vehicles?
Consumers get the same voltage
-------------------------------------- -------------------------------------------------- ---------------
difference between direct and alternating current.
In AC polarity change to
in DC does not change itself.
------------------------------------------------ --------------------------------------
task of connecting rod
ant : transfer
force of the piston to the crankshaft
--------------------------------- -------------------------------------------------- ---
What are sensors and actuators?
ant:
sensors: Have the task state operation example (engine speed, engine temperature, speed) to record and convert it into electrical signals and gets to control forward.
Examples:
solenoid valve, EinspritztVentil, ABS sensor, camshaft sensor,
actuators: receive electrical signals from control unit to induce mechanical, electrical, hydraulic or pneumatic operations.
example
speed sensor, temperature sensor,

purpose of the oil filter.
sophisticated pollution, dust and dirt particles filtered

What is an ignition of the Fuel-air mixture in the combustion chamber of a four-stroke gasoline engine is achieved with safety?
In OT (upper dead point) in the combustion chamber spark plug generates a spark, this will fuel / air mixture ignites.
------------------------------------------------- -------------------------------------------------- -
generator principle.
In the magnetic ignition and magnetic generators the electrical energy is generated by rotating Magnette.
ant 2:
movement of a magnet or a sink to another.
------------------------------------------------- --------------------------------------------------
effect of a defective Generaltorkontrolllampe?
running away no pre-excitation current, thereby inducing the magnetic field can not supply and battery is not charging.
------------------------------------------------- -------------------------------------------------- -
From what sizes the amount of voltage generated in the generator depend on?
size of the magnetic field, speed and winding.
------------------------------------------------- -----------------------------------
Moved expectation for operating temperature, engine cooling is in large circulation, consumption of fuel is greater.
---------------------------------------------- -------------------------------------------------- -
What is the electrical resistance of a conductor depend?
of the material, the cross-sectional area, length and temperature of the conductor.
----------------------------------------------- -------------------------------------------------- -
tasks of relay?
A relay with a small working current, a large shunt.
------------------------------------------- -------------------------------------------------- -----
What are the requirements to Bremsflusigkeiten?
water resistance and boiling point.
------------------------------------------- ------------------------------------------------
What ensures that the coolant boiling in a closed system only at a temperature of eg 112 ° C?
of glycol-water mixture
--------------------------------- -------------------------------------------------- -----------
term self-discharge and sulfation of a battery.
Not used a battery, it loses the time a part of the stored energy.
sulfation is a slime layer on the bottom of the battery cell einsteht is when high a short circuit.
----------------------------------------------- -------------------------------------------------- ------
What is an electromagnet?
a sink, inside which a magnetic field.
--------------------------------------------- -------------------------------------------------- ---
What good are multigrade oils?
with multi-grade oils can be seen in different temperatures year run, is kept at special temperatures well lubricated.
other words in cold temperature oil is thin, and thick-liquid at warm temperatures.
